The flipper circuit uses two voltages, one for pull-in (50V) and another for hold (8V). The transistor controlling the pull-in voltage (Q9) was shorted, leaving the high-power on to the coil, blowing the fuses. Replaced the transistor and the flippers worked.

I replaced many burned out lights. There are two rows of lights (in the 8×8 grid) not working. The transistors looked fried, and it looked like the board had also been hacked. Many GI lights on the backbox were not working too. Someone had re-wired some of the GI lighting bypassing one of the boards. Some of the ramp diverters are not working, so you never get the Hat Trick. The owner was not interested in fixing these issues! The machine needs to be “shopped”, but it is still being used in a bar.
